SPECIFICATION forming part of Letters Patent No. 685,162, dated October22, 1901.

Application filed February 7, 1900. Serial No, 4,369. (No model.)

Toa/ZZ wholly, it may concern:

Be it known that I, ANDREW E. MILLER, a subject of the Queen of GreatBritain, residing at the city of Baltimore, in the State of Maryland,haveinvented certain new and useful. Improvements in Broom-SewingMachines, of which the following is a specification.

The objects of this invention are to improve broom-sewing machines, andparticularly the machine'for which United States Letters Patent weregranted to me on January 31, 1899, No. 618,798.`

The present improvements relate to devices for supporting the'binderduring the operation of sewing the broom, to the feeding mechanism foradvancing the broom during the sewing operation, to devices forautomatically lowering the broom after each row of stitches to adjust itfor the succeeding row of stitches, to means for staggering the stitchesin adjacent rows, and to other improvements in details, all of whichwill be described in the following specification.

In my copending application, Serial No. 4,370, filed February 7, 1900, Ihave embodied certain features which are illustrated in this case, butnot claimed herein.

In the accompanying drawings, Figure 1 v is a front view of the machine.Fig. 2 is a side view. Fig. 3 is a side view of the vise and connectedmechanism upon an enlarged scale. Fig. 4 is a front View ofthevise-frame and vise, partly in section, on the line a a of Fig. 3. Fig.5 is a side view of the vise, partly in section, on the line b b of Fig.4. Fig. 6 is a plan view of the vise-feeding devices. Figs.v 7 to 12,inclusive, illustrate details.

The general construction and operation of the broom-sewing machineillustrated in the drawings are described in the patent above mentionedand it will only be necessary in this speciiication to describe theimprovements. constituting the present invention. The principal parts ofthe machine comprise the main frame A,the swinging vise-frame B,carrying the vise and the vising mechanism, rocking arms C, whichlreciprocate the needlesE upon guides F, a driving-wheel G, and aclutchHior engaging the driving-wheel' with the power-shaft I. The armsC are driven Ition of Fig. 6.

by a crank-pin on a disk J, mounted on the shaft I. y

The oise-feeding mec7zam'sm.-The visejaws K are hinged to the vise-frameB and adapted to be closed, as in the prior patent mentioned, by meansot' a treadle L. The vise-frame is mounted on trnnnions M and islprovided with a counterweight N. A suitable spring l tends to throw thevise forward 6o' into the position shown in Fig. 2. To the npper part ofthe vise-frame is attached a rack 2, having long teeth, which arepreferably radial to the axis upon which the vise-frame rocks. The rack2 is connected to the inner 65 vise-jaws 3 and moves vertically withsaid jaws. The connection between the jaws and the rack may be made inany suitable manner. As shown in Figs. 3 and 4, the rack is connectx edto a sliding piece 4 on the outside of the 7o vise-frame,which slide isconnected to an arm 5, projectingfrom the collar 6. The collar 6 isconnected with the inner vise-jaws by links 7. The rack 2 is adjustablyconnected to slide 4 by means of vbolts 4a, which pass through 75 slots2a in said rack. As shown in Figs. 2, 3,

land '6, two pawls 8 and 9 coperate with the rack 2. The pawl 8 is amoving pawl, being onvone arm of a lever 10, which has a pin- 14. Thepawl-lever 10 is normally held in 85 the position shown in Fig. 6 bymeans of a spring 15. Below the pawl-lever 10 is a lever 16, carryingthe holding-pawl 9. The lever '16 bears on a cam-disk similar to disk12'and provided with cam projections 17, which are 9o diainetricallyopposite and midway between the projections 13. The cam projections 13and 17 may of course be upon one disk, the projections 13 being in ahigher planev than the projections 17. The lever 16 is provided 95 witha spring 18 to hold it normally in engagement with the rack, andaisowith a handle 19, by means of which the rack may be released whendesired. The operation of the pawls 8 and 9 will be evident from aninspecroo When the cam-lever 16 is thrown out of engagement with therack by means of the cam projections 17, the rack is thrown forward bythe spring 1, connected with the vise-frame. The pawl 8 is carried withthe rack, the pin-and-slot connection 1l permitting it to movesufficient to carry the rack forward one tooth. T he pawl 9 immediatelyrengages the rack and holds it, and when the shaft 14 makes aquarter-turn the pawl 8 is thrown out of engagement with the rack andimmediately drawn back to engage a new tooth by means of the spring 15.

It is necessary in producing perfect work that the stitches in adjacentrows should be staggered, and I have provided devices for locating thestitches of each row half-way between the stitches of the adjacent rows.As shown in Figs. 2 and 3, a shield 2O is adjustably connected to therack 2 by means of bolts 21, which pass through two series of holes 22in the shield-plate. The shield has a radial edge 23, which can be madeto cover one or more of the teeth at the front edge of the rack toprevent the pawls engaging with said teeth. In the edge 23 are recesses24, which uncover one additional tooth. It thus follows that when thepawls are opposite the recesses the stitching begins one tooth or stepnearer the edge of the broom than when the pawls encounter the radialedge 23. As the pawls permit two teeth to escape for each completestitch, it follows that the stitches in one line will alternate withthose in the adjacent line, thus carrying the staggering uniformlyacross the broom. On the rear edge of the feed-rack are filling-pieces25, which may be formed integral with the rack-frame,as shown, or madeseparate and removably secured thereto, like the guard-plate, and whichprevent the pawls from engaging the last tooth 26 on alternate lines ofstitching. The guardplate is adjustable to sew seams of differentlengths on brooms of different sizes. As the rack-teeth are radial ordivergent and the rack is movable radially or transversely with respectto the pawls, it follows that the release of one tooth will permit thevise to move through a shorter arc when the rack is raised than when itis lowered. Hence the stitches in successive rows will increase inlength as successive rows will correspondingly inthe rack is dropped,and the lengths of the crease, assuming the same number of teeth to bereleased by the pawls in the several positions of the rack. If the teethwere parallel, the stitches would be the same length in different rows,and it would be necessary to permit the pawls to engage a greater numberof teeth in the successive positions of the rack in order to increasethe length of successive rows of stitches.

Automatic start/ng mcchtmfism.-A spring 27, Fig. 2, which is connectedto the clutchlever 28, constantly tends to throw the clutch H intoengagement with the drive-wheel G. When the machine is stopped, theclutch is held out of engagement by arm 29, which engages a shoulder 30on abar or frame 31, conees,

`of the rack, Fig. 9.

nected with the clutch-lever. The arm 29 is.'

mounted on a shaft 32, upon which is a second arm 33, having a pin 34 inthe path of a lever 35, pivoted to a bracket of the main frame at 36.The upper end of the lever 35 has an arm 37, Fig. 2, adapted to beengaged by the adjustable guard-plate 20 when the vise is thrown backinto the position tobegin arowofstitches. Thearm 37 engages the radialedge 23 or one of the recesses 24, depending upon the heightto which therack and the inner vise-frame are adjusted. It therefore follows thatthe automatic starting of the machine is eected at the proper time tobegin any seam on either a large or small broom, respectively, thestarting being effected by the same part which regulates the number ofstitchesthat is, the adjustable guard 20. The startinglever 35 is heldnormally in the position shown in Fig. 2 by a spring 38. A suitablebuffer 39 is provided to take the shockimparted to the lever by thevise-frame. When the vise-frame is thrown back, the lower end of thestarting-lever is thrown forward, thus operating the arm 33 and throwingthe pawl 29 out ot' engagement with the stop 30, thus permitting thespring 27 to operate the clutch and start the machine.

Automatic .Stopp ing mechanism. Connected with the vise-frame is an arm40, the lower end of which, as illustrated, is pivotallyconnected to oneof the trunnions M, while the upper' end is connected to the rack 2 byapin 41, which engages a zigzag slot 48 in the back On the upper end ofthe arm 40 is a switch device attached to a horizontal extension 42 ofthe arm. The extension 42 has an inclined or cam surface 43 and abovethis surface a plate 44, havingaspringtongue 45, overlying theincline 43and in line with the uppersurface 46 of the forward end of the extension42. The plate 44 is adjustably connected to the arm 40 by means ofscrews 47, passing through slotted openings in the plate. The free endof the spring 45 is located close to the upper end of the incline 43, asshown in Figs. 7 and 8. The

clutch is thrown out of engagement with the' drive-wheel by means of anarm 51, carried by a vertically-movable rod 50. The arm 51 carries aroller 52. The upper end of the rod 50 is connected to a lever 53,pivoted to the frame of the machine at 54, the forward end of whichlever has a projection 55, adapted to ride on the incline 43 during therearward movement of the vise and on the spring-plate 45 during theforward movement of the vise. A spring 56 constantly tends to raise therod 50 to bring the roller 52 on arm 5l into the path of a pair ofdiametrically opposite cams 57 on the rear of the disk J.

The operation of the stoppin g devices above described is as follows: Asthe vise-frame is thrown backward to carry the broom to the sewingmechanism the forward end 55 of lever,53 rides up the incline 43 ontothe forward upper surface 46 of the arm 40. The

IOO

IIO

bracket 49 upon the clutch-operating frame 3l moves said frame 3l to therear and disengages the clutch. A spring 58, Fig. 3,

throws the stop-arm 29 up in front of the stop` 30 and locks the clutchout of engagement.

As the stitches in each line of stitching are staggered or alternatedwith relation to the stitches in the adjacent line or lines, it followsthat the last stitch in certain lines will be nearer the edge of thebroom than the last stitch in the alternate lines, and it isthereforedesirable to varythe stoppage of the machine to correspond with the laststitch in each seam. This is accomplished by means of the zigzagguide-groove 4S in the rear of the rack-plate 2, which grooveautomatically adjusts the stop-arm 40 as the rack plate moves down stepby step for the successive rows ofst-itehing, as will be evident frominspection of Fig. 9.

To effect the promptl stoppage of the machine, a brake-shoe 59 islocated under the disk J, being supported and guided by springconnections 60, Figs.v5, 10, and ll. A short toggle-lever 6l connectsthe frame 3l with the brake, the length of the toggle-lever being soadjusted that the rearward movement of the frame 31 will apply the braketo the disk J. The frame 3l consists of two bars, and the lever 6l isadj ustably connected to a cross-piece 62, which is pivotally connectedto said bars, as shown in Figs. 10 and ll.

Automatic broom-dropping mechanism.- After the last stitch is taken in aline of stitching the vise-frame is released from the feedpawls andthrown into its forward position by the spring l. This movement eectsthe automatic opening ofthe vise K by means which are fully described inmy prior patent and need not be herein specified in detail. When a newbroom is inserted, the inner visejaws, which constitute thebroom-support, are raised to their highest position by means of a forkedlever 63, which engages the collar 6,

' connected to the inner vise-jaws by means of links 7, Figs. 4 and 5.The inner vise-jaws are sustained in the elevated position by apawl-lever 64 and a rack 65, having adjustable teeth connected to theslide 4. The rack comprises a series of bars having projecting teeth 66at their lower ends, said bars being located in a recess 67 in the slide4 and clamped therein by a plate 68 and suitable bolts. The teeth of therack are adjustable to vary the distance between rows of stitching. Thepawl-lever 4 has a broad engaging pawl 69, adapted to engage any one ofthe teeth 66, and` pressed into engagement with said teeth by means of asuitable spring 70. yThe lower end 7l of the pawl-lever extends into thepath of a swinging arm 72, attached to a block 73, connected to a collar74, sliding on thetubular shank of the rvise-frame. The pivoted arm 72engages and operates the pawl-lever 64 as tho collar 74 descends; but itis free to swing back and out of the path of the pawl-lever as thecollar 74 rises. The collar 74 is connected, by means of togglelevers 75and levers.76, with the jaws ofthe vise K, and said collar is lowered toopen the vise and raised to close it, as described in the patent abovereferred to.

The operation of the broom-lowering devices will be apparent from theabove description and need only be briefly recapitulated. When a newbroom is inserted in the vise, the inner jaws 3 are raisedpuntil thelowest tooth 66 of the rack 65 rests upon the pawl 69. The vise K isthen closed and the first seam sewed. When the vise K is opened, thepivoted arm 72 engages the pawllever momentarily and permits the rack-615 and its connected parts, including the rack 2 and the innervise-jaws 3, to drop one tooth, the pawl 69 engaging the next to thelowest tooth of rack 65. This is repeated for each, seam, the droppingof the broom being entirely automatic. The slide 4 and its connectionsare guided by means of a rod 77, which slides in an opening in theframe, and a fixed rod 7 S, which passes through an opening in theslide. Y

Devices for supporting the binden-Pivoted to the vise-frame are a pairof fingers 79, which are curved inwardly at their upper ends and causedto impinge upon the opposite ends of the broom by a spring S0. Theinwardly-turned tips 8l of the fingers 79 are located slightly above theedge of the visejaws in order to support the binder at a sucient height`to permit the needles to pass under it. The lower portions of thefingers 79 are inwardly curved, forming cams 82, whichcams are engagedby vertically-movable rods 83, attached, by means of connecting-pieces84, Vto the collar 74, which operates the visejaws. When the collar israised and the visejaws close, the spring-fingers are freed from therods 83, and they close upon the broom, as shown in full lines in Fig.5. When the collar is drawn down to open the vise-jaws, the rods 83engage the cam-faces of the tingers and throw the finger-tips away fromthe broom, as shown in dottedv lines in Fig. 5. The binder-supportingngers are therefore operated automatically. The lower portions of thecam-surfaces S2 assume a vertical direction when the fingers aresufficiently open, and the continued downward movement of the rods 83after reaching these vertical portions of the cam-surfaces 82 do notcause any further separation of the iinger-tipsrSl.

As shown, the sliding collar 74, which op- IOO erates the vise-jaws, isconnected to a treadlelever 85 by means of links 86, the treadleleverbeing mounted on a shaft 87. Upon the shaft 87 is a hand-lever 88, bymeans of which the vise may also be operated. On the shaft 32 is anotherhand-lever S9, by means of which the stop-arm 29 may he thrown out byhand to start the machine.
